Reading Karl’s great blog post on repairing a kijiji’d synthesizer, I thought about how sad the original owner must have been when he smoked his nice Korg Poly-800 MKII just by plugging in the wrong power supply. I also thought about how avoidable this is and all the things I’ve had to figure out about power bricks in my travels as an electronics scrounger/repurposer.
Wouldn’t it be great if manufacturers clearly labeled power jacks on their devices with
- (a) polarity
- (b) input voltage
- (c) required current, and
- (d) if the input voltage needs to be regulated?
